Hodge dual operator
NettetThe Hodge dual is the unique isomorphism ⋆: Ωk(M) → Ωn − k(M), ω ↦ ⋆ ω such that the following holds: ∀ω, η ∈ Ωk(M): ω ∧ ⋆ η = ω, η vol where vol: = √g dx1 ∧... ∧ dxn is the … Nettet19. aug. 2024 · $\begingroup$ I don't think what you wrote about the definition of the dual by lowering indices is correct. A tensor with lowered indices is just the same tensor with lowered indices, and it is definitely not the same as the [Hodge dual][1], which is what you get when you contract with the Levi-Civita tensor, and is the correct definition of the …
